IMPRovEMENT IN PAINT-BRUSH.

4 The Schedule referred to in these Letters' Patent ani'makrxg part of the same.

To all whom it may concern l Be it known lthat we, ALVIN MGDONALD and J AMES M. WHITE, both ot Washington, in the county of Tazewell, in the State of Illinois, have invented a new and useful Device for Securing the Bristles to the Shell or'Handle of a Paint-Brush; and do hereby de- Aclare that the following is a full, clear, and exactA dcscription thereof, reference being had to the annexed drawing making a part of this specication, in which like letters of reference refer to like parts,`and in which- Figure l represent-s a vice and brush.

Figure 2, a superficial view of the' half disks Figure 3 represents the carriers or supports of the halt' disks, from above.

Figure 4, longitudinal elevation-of the latter. Figure 5', vertical section of the whole brush. This invention relates to a device for the removal' perspective View of theu de- Vofthe worn out bristles in paint-brushes, or similar tools.

A represents the handle of the brush.

l5, a shell or bristle-holder, with a socket, g, beneath, which inc-loses the handle A.

C C, two small half disks, of metal, with segment-al slots a a, a. a parallel with the curves, and with chamt'ercd segmental centers d d.

D I), two carriers or supports for the half disks, placed parallel with each other, and to which they are attached by means ot' pins, rivets, or screws 11 b, one

at `each end'of the cari-ier.7 Each screw or pin is securely fixed in the carrier, and passes upward through and works freely in its respective slot in the hall' disk.

Au olset, f, is below each carrier.

E is a cou'e,'or a screw with a conical head, which,` on 4turning the screw, (which of' course passes between or in the center of the device just described, C C, D 1),) into tle handle of the brush, securely fastens the whole device. l

rlhe operation of this invention is as followsz' The cone E is inserted, by its point,into the orice d d, between the half disks, and a turn or' two given tothe screw F, which passes through it; the bristles are inserted around the shell or bristle-socket'B,

and the screw is then made tight, forcing the cone downward, and against the halt `disks and their carriers, thus expanding the parts and holding the bristles. The segmental slots aa a a causethe equal expansion, in connection with their respective'pins b,

Src., of the bristle-holder C C D D. The-offset f, be-

neath each 'of the carriers D D, offers a recess, in which-the ends of the bristles are clinched, as it were, and prevented from withdrawing.

The bristle-holder, when constructed of the pieces C C, with their slots a aand segmental centers-d d, the carriers D D with pins b b'b b, or equivalents, and their segmental centers e` e, and their offsets or bases f f, combined with the cone E, or equivalent, screw F, handle A, bristle-shell B with its socket g, and bris,- tle-s G, substantially asand for the. purposes described.'

In testimony that we claim the foregoing paintbrnsh, we have hereunto set our hands this 14th day of June, `1870.
